To all whom it may concern:4

Be it known that I, WALTER C. 471mgwAY, of Rockford, county of Winnebago, and State of Illinois', have invented certain new and useful Improvements in 'Carbureters and the Like, is a description.

My invention belongs to the general class of devices designed and a suitable liquid, such, for example, as a hydro-carbon, for any desired pur ose, and has for its object the production o a sim le ,and ellicient means for the purpose -which will thoroughly and perfectly accomplish the object sought.

To this end, my invention consists in the .novel construction, arrangement, and comhcrein shown and lebinution .of parte t particularly pointed 'out scribed, and more in the claims.

In the drawings, wherein like reference characters iiulicate.like er corresponding purtsz--liigure 1 is n central vertical section through my device. Fig..2 isa bottom plan of thc same. Fig.' 3 is n. bottom plan of the sumewith the air and liquid valves and the bottom closure removed.' Fig. 4 is u plan view. of the bottom closure ofthe shell removed from its seat. Fig. 5 is a bottom plan of the liquid valve. Fig. 6 is a central vertical section of `the bottom art of :i mmlifed foi-rn of my device, and Fig. 7

The part is also annular, liigan opening 8 which serves as an 'the air, and is provided with an outwardly extendingrflange 9 constructed to besnugly seated in a corresponding reof which the followingV to commingle air or gus any preferred 'manner'.

A spring 16 resting set .or extension-12, andl a, pin 17, or equivalent pai-1'.,y on the stein, resiliently hold the valve to its seat. A duct 18 servesA to-eonduct the liquid 'from the supply ipe I19 to the valve 14,1' ich4 is rovid Awithin' groove 201 forme inI its ace which, closing' `inst the valve-seat forms a lduct for-the liq'uid. The oove 20 is peculiarly formed, being sligli y eccentric. tothe valve regularly increased in size from one tothe o er, and, for lconvenienoe, gay ge) termed an Increasingspira groove duct 2 1 formed in the va ve-seatand extending from a point inV the groove 20 tothe annular inlet vserves to pondu@ h6- liiliiid to 'the shell.

Bythis means, fluid is delivered to the shell in a' ring inclosin the nir-inlet '8, for a urpose herein descrilzire'd.Y In the ferre form, a `valve of any suitable construction is emplo ed to controlthe admissionof air throng the a liutter-,valve`22 serves this pu It is desirable that the roportions of liqiiidand air may be uniiirmly maintained in op'erating the device, hence I prefer to so connect the valves 14 and be operated synchronously. secure an arm 23V s tem 15 to form. neet the valve 22 thereto by a equivalent means. It will thus that the o ation of the valve 14 correspon ing operating of the `air-valve.

justing theposition of the erin 23 on the sterrl,15,.the set-screw serv1ng to firmly maintain the .)arts in their adjusted pos1 tion. A handle 2G secured to the stem 15 Vserves as means for operating the valves.

Within the shell or mixing chamber, means are provided to securea thorough commingling of the inlowing liquid and air, In the preferred construction, the bottom of thcshell is concave or spheriform,

, and the correspondingly formed spreader or delleclor 2l' loosely fitting therein, cooperates therewith in the operation ofthe device. The deflcctor 27 is vertically movable, nor-- n ially resting in such a position as to tend to close the inlets 7 and 8, and to prevent the iiil'low of both liquid and-air. The operil ation of the engine. or u coperating p'umi) to which the device is htteched,however,wi l tend toproduee a 4partiel vacuum in-t'he mixing chamber, momentarily lifting the deliector und providing a narrow channel between the exterior surface of the seme end the annuler inl the interior of the shell. Thesnme act-lon permits' the in wing of the liquid through .7, and the air throu h t e inlet 8, the current of air Ybeing directe over the ring of fluid, taking up a uantity thereof, and filling the chamber wit. Vthe mixture. As the deflector 27 assumes its normal position, it contacts with the ring of'uid, tending to spread the same out evenly' into athin film between, and coating the surfaces of, the` proximateV arts formin the channel between the vde eetor and t e chamber and again closingg-the inlets.' This action obviously thinly spreads the liquid over a com-.

paratively large area,`comprising the exterior surface of the deflector and -the -interior surface of the shell over. whieh eren.A the regulated current of inliowing air is periodically and evenly directed' by the .pulf

.eating operation of the deyice.

Any preferred means may be employed for suitably guiding the operation of the deliector. As shown, a plnte 28 suitably supported within the shellA receives the end of the uide 'post 29,` whi-c the lower 'part of the ef'leetor isprovided with extensions 30 V positioned within the opening4 8. A coil spring 31 positioned between u shoulder 3 2 on the guide post 29, and the plate 28, or..

4 equivalent means serves to resiliently maintain the deflector in 4its normal position; 'The deil'ecton is preferably' substantialiy closed atthe top `to prevent the4 accumula tion of fluid therein. If" desired, a. system,

of baille-plates 3B', 34,- may be empio ed to secure a more thorough mixture of tie as and iuidin' the shell, und the plate Q'Sgis preferably also formed to serve es one ofthe series of baille plates for thatl urpose. .7

As shown in Fi C und 7,the ottom of the shell is liet, w lilethc liquid inlet 35 is lengthened to distribute the inliowing liquid ,to mix a disin Y the air rated over'a.coniparati\'ely large aree. An apernture 36, of considerable s izc,l is formed throu rh the spreaden?, Awhile the air inlet 38 is ormed in the side of thel shell, end is adapted to be closedV b the edgeof the spreader. The liquid inet is interposed between the air inlet und the aperture, so that the inllo'wing nir will be directed over the inflowing liquid. The operation of the spreader is substantially the same, et each operation the liquid is mechanically spread over the proximate surfaces of the spreaderund bottom of the' shell, overwhichthe cur- -rent of flowing air is directedfescialping as limiting myself to' the use of the device for carburcting purposes only. It is alsoY improvement forms a.; Vtriple valve devi'ee,`in which thevalve 14 or apparent that my equivalent `means controls the flow of4 liquid und the'vfllve 22, the flow of air, while the deflecior 27 forms u. third' valve which Vnutomatically controls the entrance of both liquid and air in the mixing chamber. A
